Provided is a sputtering apparatus which deposits a metal catalyst on an amorphous silicon layer at an extremely low concentration in order to crystallize amorphous silicon, and particularly minimizes non-uniformity of the metal catalyst caused by a pre-sputtering process without reducing process efficiency. This sputtering apparatus improves the uniformity of the metal catalyst deposited on the amorphous silicon layer at an extremely low concentration. The sputtering apparatus includes a process chamber having first and second regions, a metal target located inside the process chamber, a target transfer unit moving the metal target and having a first shield for controlling a traveling direction of a metal catalyst discharged from the metal target, and a substrate holder disposed in the second region to be capable of facing the metal target. A distance difference between a linear distance, which is a distance between a substrate loaded on the substrate holder and the metal target, and a length of the first shield is less than 3 cm.

An inspection system using a scanning electron microscope includes a scanning electron microscope chamber inspecting an object to be inspected by using an electron beam and maintaining a vacuum condition, a stage positioned below the scanning electron microscope chamber to be separated therefrom and mounted with the object to be inspected, and a transverse guide transferring the scanning electron microscope chamber on the stage. Atmospheric conditions are maintained between the scanning electron microscope chamber and the object to be inspected. Accordingly, object to be inspected a large size of an object to be inspected may be inspected without damage to the object to be inspected such that a cost reduction and a yield improvement may be realized.

Inspection system using scanning electron microscope

A substrate processing apparatus that forms thin films on a plurality of substrates and thermally processes the substrates, by uniformly heating the substrates. The substrate processing apparatus includes a processing chamber, a boat in which substrates are stacked, an external heater located outside of the processing chamber, a feeder to move the boat into and out of the processing chamber, a lower heater located below the feeder, and a central heater located in the center of the boat.

Substrate processing apparatus

An apparatus for thermally processing a plurality of substrates including a process chamber into which a boat having a plurality of substrates stacked thereon is loaded, and a heater chamber separate from the process chamber and having a plurality of heaters to apply heat to the process chamber. Here, the heaters are installed to correspond to all sides of the plurality of substrates. Therefore, it is possible to minimize a temperature distribution in the process chamber and uniformly supply heat to the entire region of the plurality of substrates.
